1 . Having learned about electromagnetic radiation in this lesson , which of these statements about it is true ?
2 . In terms of wavelength , which of these is the longest ?
3 . Which of the following statements is true about atomic size ?
4 . Geometrically linear means that the electron groups have what angle ?
5 . Geometrically trigonal planar means that the electron groups have what angle ?
6 . Some atoms are better at attracting electrons compared to others . Which term below best describes that ?
7 . You have been given a 0.325 L canister containing a gas . The pressure gauge on the canister reads 721 mmHg , and the temperature gauge reads 305.15 K . The piston on the canister was pushed to compress the gas to 0.286 L , thereby increasing the pressure to 901 mmHg . What is the new temperature in Celsius ? Remember sig figs .
8 . I have a pressure cooker in my underground lair that is brewing a diabolical solution . I set everything up and went upstairs , but forgot to write down the initial temperature . I know the starting volume was 1.00 L . When I came downstairs later to check on it , I see that the volume increased to 1.10 L , and thermometer read that the temperature was now 528.15 K . What was the starting temperature when I left ( in ° C )?
9 . Think back to Lesson one when we talked about density . Now think about it--my kids love balloons , and then are always laying around the house . Suppose one was laying by the window at night when they went to bed , but the next day , when the sun came up , it warmed the gas ( air ) that was in the balloon . What would be true about the density of the air in the balloon ?
